The present invention is described in detail.
Referring to figs. 1 to 4, a kind of battery pack heat management device, comprising: thermally conductive row 1, refrigerant tubing 2, refrigerant
Compressor and fluid pipeline 3.Wherein, thermally conductive row 1 and battery core group thermal conductive contact；Refrigerant tubing 2 is set to the thermally conductive row 1
It is interior, and extend along the length direction of the thermally conductive row 1；Coolant compressor is connected with the refrigerant tubing 2, the battery core
The temperature of group is higher than the first setting value, and the coolant compressor is pumped into refrigerant into the refrigerant tubing 2；Until described
After the temperature of battery core group is lower than the second setting value, the coolant compressor stops being pumped into refrigeration into the refrigerant tubing 2
Agent；Fluid pipeline 3 is set in the thermally conductive row 1, and is extended along the length direction of the thermally conductive row 1, the fluid pipeline 3
Inside it is passed through the first liquid.
Specifically, in battery pack heat management device of the invention, thermally conductive row 1 and battery core group thermal conductive contact be may be implemented
Heat transmitting and heat exchange to battery core group.Wherein, refrigerant tubing 2 and fluid pipeline 3 are set in thermally conductive row 1.2 He of cryogen pipeline
Cryogen pipeline 2 and fluid pipeline 3 are set the length along thermally conductive row 1 by the heat transfer effect of liquid and battery core group in fluid pipeline 3
Direction is spent to extend.In this way, cryogen pipeline 2 and fluid pipeline 3 increase length, the liquid flowed through inside it is made to increase basin face
Product can carry out more heat exchanges with battery core group.Coolant compressor is connected with refrigerant tubing 2, and the temperature of battery core group is high
It is pumped into refrigerant in the first setting value, stops being pumped into after the temperature of battery core group is lower than the second setting value, it is ensured that battery core group
Work is in a suitable temperature range.The first liquid in fluid pipeline 3 be it is immobilising, may be implemented battery core group carry out
Heat is stored during exothermic, and battery core group is heated when the temperature of battery core group reduces.Battery core may be implemented in the device
Group when the temperature is excessively high radiates in time to battery core group, heats when battery core group temperature is too low to battery core group.The device energy
Consume low, heat exchanger effectiveness is high, and when work is safe and reliable.
Wherein, coolant compressor is connected with refrigerant tubing 2, and the temperature of battery core group is higher than the first setting value, refrigerant
Compressor is pumped into refrigerant into refrigerant tubing 2；Until after the temperature of the battery core group is lower than the second setting value, the refrigeration
Agent compressor stops being pumped into refrigerant into the refrigerant tubing 2.During the battery of electric car is charged, especially
It is during carrying out quick charge to electric car, and battery core group can generate a large amount of heat.Although thermally conductive row 1 can play centainly
The ability of heat dissipation, but the heat generated during being far from satisfying quick charge.Firstly, the first liquid in fluid pipeline 3
Body can absorb a part of heat during battery is charged, and reduce the temperature of battery core group to a certain extent.But with
The progress of charging process, the first liquid in fluid pipeline 3 cannot play the role of cooling.So in thermally conductive row 1
Refrigerant tubing 2 is offered, makes wherein be passed through the heat dissipation that refrigerant accelerates battery core group.Coolant compressor and refrigerant pipe
Road 2 is connected, and can continue to be passed through refrigerant into refrigerant tubing 2.Refrigerant can largely absorb the heat transmitted via thermally conductive row 1
Amount, takes away the heat of battery core group, so that battery core group achievees the purpose that fast cooling.Prevent battery core group from damaging because of high temperature,
And avoid since height temperate zone carrys out a series of generation of unfavorable conditions such as automobile short circuit, allow battery core group maintain one compared with
For stable, higher working temperature environment.
In addition, coolant compressor stops pumping into refrigerant tubing 2 after the temperature of battery core group is lower than the second setting value
Enter refrigerant.Because battery core group needs a higher temperature environment just to can guarantee higher charge-discharge electric power.High temperature will affect
The safe handling of battery core group, but low temperature can reduce the working efficiency of battery core group.So the temperature in battery core group is set lower than second
After definite value, coolant compressor stops being pumped into refrigerant into refrigerant tubing 2, in this way can be to avoid battery core group by refrigerant mistake
Mostly take away heat, operating temperature is maintained at lower level.So the temperature controlled refrigerating agent compressor for passing through battery core group is
The no refrigerant that is passed through into refrigerant tubing 2 can guarantee that battery core group is in a suitable temperature levels, so that battery core group is not
It can be because high temperature generates damage, situation that will not be low because of low temperature generation efficiency.
Wherein, the first liquid is passed through in fluid pipeline 3, the first liquid mainly includes water.First liquid is in fluid pipeline 3
Portion is not flowed, the medium as storage thermal energy.During battery core group is discharged, a large amount of heat can be generated.If not setting
The battery of fluid pipeline 3 is set during exothermic, heat can be lost to the external world.However, fluid pipeline is arranged in thermally conductive row 1
3 and after being passed through water, with the electric discharge of battery core group during, the water in fluid pipeline 3 absorbs what battery core group discharged by thermally conductive row 1
Heat, the liquid such as water in fluid pipeline 3 are heated continuously.That is, a part that battery core group discharges during discharge
Heat is absorbed by the water in fluid pipeline 3.In the case that battery is without work, the temperature of battery core group can decline quickly.
But after the water in fluid pipeline 3 absorbs the heat that battery core group discharges, cooling battery core group can be heated.Due to water
Specific heat capacity it is very big, it is possible to battery core group is heated for a long time.In this way, when under cold temperature conditions, electronic vapour
After the flame-out parking of vehicle, the temperature of battery will not reduce at once, and the water in fluid pipeline 3 can carry out certain time to battery core and add
Heat, so that battery core is in a higher temperature range.When electric car is again started up, battery core can with higher efficiency into
Row work.In addition, since the heat of the water storage in fluid pipeline 3 is the heat for working normally release by battery core group, not
Have and increase the additional power consumption of vehicle, and good heating effect is played to battery core.

The volume of the liquid such as the water deposited.Two 3 scattering devices of fluid pipeline, two fluid pipelines 3 can be absorbed on thermally conductive row 1 not simultaneously
With the heat of position, the approach that thermally conductive row 1 transmits heat to fluid pipeline 3 is increased, the water in fluid pipeline 3 can be absorbed more
The heat that the excessively thermally conductive row 1 of multi-pass transmits.
